Speaking of the automobile lamp group, we will have halogen, xenon and LED lights in our minds. Now car LED lights are becoming more and more popular, so what about LED lights? What are the advantages and disadvantages? The following small series for everyone to introduce.

Advantages of automotive LED lights

1, long life. Generally can use tens of thousands or even more than ten thousand hours, because LED is a semiconductor component, and unlike incandescent lamp, there is no glass, tungsten filament and other vulnerable movable parts, the fault is very low.

2, energy saving. The LED light source can directly produce the color of red, amber and other colors needed by automobile lamps without loss of color, and the utilization rate of electric energy is as high as 80%.

3 、 green lighting source. The LED spectrum has the advantages of good color, no excess infrared and ultraviolet spectrum, no mercury harmful substances, little heat and radiation, and belongs to the green light source.

4. High luminous purity. The color is bright and bright, without shade filter, the light wave error is within 10 nanometer.

5, small size. LED takes up a small footprint, and the designer can change the lamp model at will and make the car model diversified.

6, lit without delay. The lamp has fast response and is only 60 nanoseconds, especially suitable for the light source of automobile lamps.

7, good color. Color saturation of 130%, full-color, so that the lights are more clear and soft.

8 、 low voltage safety. LED, the first electronic version, needs only the DC voltage 12V to light it up.

9, low brightness attenuation. LED high brightness, light attenuation is far lower than halogen lamps, suitable for lighting and brake lights, lights and other warning lights.

Disadvantages of automotive LED light

1, high cost. LED lights are much more expensive than ordinary lights, but with the development of technology, LED and other applications are becoming more and more common.

2, poor heat dissipation. Heat dissipation of heat treatment is not good, not easy to decay, affect the service life.

3, the management is not standardized. LED lamp product quality is not guaranteed.

4, poor color rendering. Car LED headlight bulb poor color, often a dark yellow color, the feeling is not very comfortable.
